Unpatterned

Small steps; they look alike until they are all over the wall, and then it’s too late. Test pots good (get the dinky little rollers which – amazingly – actually work).

Sibirica; sometimes only for a single day before they go over.

Charity shop: supposedly 3D, but looking at the individual pieces with their shifting colour makes your eyes go googly. And disassembly is a pig, as the pieces jam together, making the image-bearing plastic delaminate from the cardboard substrate. Really glad it was a Bargain.
